I had one tell me something happening right in front of us was not actually happening. I asked him a second time, and got the same answer.
They're very very "well trained" not to acknowledge anything, and to stick to the rehearsed lines and procedures.
Welcome to Gulag America, comrade.
Another trick they try when you opt out of the xray...they say it will be a long while before they have someone available.
They told that to one guy in front of me and so then he chose to do the xray. I was traveling on business and my colleague and I opted out (AFTER the other guy changed his mind). They told us the same thing and we both replied I am several hours early so don’t mind waiting here. We were inspected and on our way BEFORE the other guy made it through the xray machine line!
